About time stamping of files:
This utility supports the function to exchange time stamp information between the transmitted file
and received file. The time stamp information to be exchanged will be processed assuming that it is
Greenwich standard time. In contrast, the time used by the IT-2000 is the local time, and the time
stamp of IT-2000 files are accordingly controlled based on the local time.
The XY utility, for file transmission/reception by means of the YMODEM protocol, will convert a
time stamp in Greenwich standard time to a time stamp in local time, or vice versa. This time
conversion is achieved according to the environment variable, TZ. In communication between two
IT-2000 terminals, if, for example, TZ of the transmission side is "JST+5", the time stamp of a file
to be transmitted will have five hours added. In this case the reception side will create a file by
subtracting five hours from the time stamp of the received file.
If the environment variable TZ is not set, this time conversion is not performed.
The time stamp made at XMODEM communication uses the system time of the reception side.

About key input during communication:
Do not press any key during communication, otherwise file transmission/reception may be
hampered.
Using this utility where COM2KEY.EXE is resident:
To use this utility where a debugging tool called COM2KEY.EXE is resident, the /N option must be
specified. Since COM2KEY.EXE will transfer the displayed characters to the COM port, the
characters displayed by this utility will also be transferred to the COM port, hampering normal
transmission.
Function and operation method
Always specify necessary start parameters. These parameters include the essential command and its
option, other parameters, and the transmitted/received file name. Each parameter must be separated
by a space or TAB code.
